So, I mentioned SOXL, a triple-leveraged ETF, that I have used as a market timing vehicle. As the semiconductor industry has a higher beta than the S&P500, SOXL can easily have 4 to 5 times the short-term fluctuation of the latter.
I currently hold 1% of portfolio in SOXL, which I accumulated in the past couple of months. It closes today at $29.77, and I have bought at a price as low as $21.50. However, as my timing was far from perfect, and I was buying it on the way down when it was higher than $21.50, at this point I only have a 10% gain on this position.
Just sold off 1/4 of it, and wrote a covered call on 1/6 of it. If that call gets exercised on May 2013, that would be a 25% gain on those shares. I still do not know what to do with the rest.
As you can see, it's just a lark with 1% of portfolio. I have had some gains with this game, and made perhaps 15% to 25% gain on investment over a trading period of up to 6 months. It was not enough money to add that much to portfolio annual gain, but a lot more interesting to me than going to Las Vegas.
